Reasons Why Samsung TV Turns Off by Itself and Won’t Turn Back On

There are a few reasons why your Samsung TV is turning off by itself. To cite the most common ones reported by users, they include:

Ruptured and Faulty Cables

The most common thing we tend to forget about our televisions is that they are connected using cables.

If either the HDMI/RGB cable or the power cord is ruptured and busted, that’s the problem.

You see, if a cable is not able to transmit all the needed data and information, it won’t work.

Hardware Problems

Our televisions aren’t invincible. As a matter of fact, they are part of the most fragile electronic appliances we have.

Most, if not all TVs have small circuit boards and panels, which are all sensitive. One common problem that TVs have is their hardware, and this can encompass the device itself.

It could be because there’s something wrong with the cables or the cords; it could be the remote or any other type of hardware or component.

Power Supply Problems

Last, but definitely not least would be power supply problems. All electronic devices and appliances have power supplies.

If this is the one that goes busted, expect your device to malfunction, especially when it comes to activating or turning it on.

Circuit Breaker/Power Problems

Take a look at the standby light because it’s something that can tell you what the problem is. Is it turned on? Is it turned off? Is it blinking?


If there’s the standby light on and it is color red, it means your television is getting power. If it’s blinking red, it’s getting inconsistent electric supply. And lastly, if it does not have any light on, it’s not getting any power.

Step #2: Check the Circuit Breaker

The circuit breaker is the component of households that control the electricity within it. You will easily be able to notice it if other appliances in your home aren’t working.

You can check the lights, the refrigerator, the microwave oven – and even the thermostat and see if it’s working.

Step #3: Look at the Status and Condition of the Wires and Cables

After checking the standby light and confirming it’s not power, check the wires and cables.

Any type of rupture or damage to either of the cables could mean that there’s less data the television is receiving.

If you have spare power cords and HDMIs, try replacing them. The problem might lie with them, not entirely the television or the electrical supply.

Step #4: Try Pressing Buttons on the Remote

If you see the standby light press the power button on your remote control. You can also try pressing the power button on the TV to see if it’ll turn on.

So, the next step is to…

Step #5: Power Cycle Your TV

Unplug the television from power for about 30 seconds to one (1) full minute. Your television needs to be completely disconnected from power.

You can do this either by unplugging it from the main outlet from the wall or by disconnecting the power cord connected at the back of your television.

After the timeframe, plug your TV back in again. If you see a red standby light, your TV is receiving power. On the other hand, if there’s no light or if there’s a blinking light, there’s an issue with power.

Doing so will assure you that your device is receiving all the power it needs to turn on.

Try to perform this 6-step process to see if your television turns back on or activates.
